FOLDING PACKING-BOX.

SPECIFICATION forming partof Letters Patent No. 233,355, dated. October19, 1880.

Application filed March 1, 1880.

To all whom it may concern:

Be it known that I, JEREMIAH H. KEAIING, of Boston, of the county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovement in the Manufacture of Folding Packing-Boxes; and I do herebydeclare the same to be described in the following specification andrepresented in the accompanying drawings, of which- Figure 1 is aperspective View of a box of my improved kind. Fig. 2 is a bottom view,

' the dotted lineg m indicating the line on which the bottom flaps foldinward; Fig. 3, a vertical and oblique section of it on linea: wot Fig.

I5 1. Fig. 4 is a representation of the pattern or form for cutting thebox from a single piece of paper or other proper material. Fig. 6 is asectional view, showing the bottom of the box in a partially-foldedposition.

The improvement relates particularly to the bottom of the box, which, inaccordance with my invention, is made in two separate parts, each ofwhich is connected to the two next adjacent sides of the box, and isadapted to fold either within or without the box and on a diagonal lineof the bottom, each of the parts, when at right angles to the sides ofthe box, lapping on the other part.

In Fig. I of the drawings the box is shown 0 as open at top and expandedfor being filled, while in Fig. 5 it is shown as contracted or foldedtogether for being packed into a small compass or arranged in a packwith others of the same kind.

The body or sides of the box is composed, as shown in Fig. 4, of arectangle, A B O I), of thick paper, which fold at right angles to eachother on four parallel lines, a b c d, the rectangular part A'D of beingintended to 0- be overlapped by the rectangular part B G g h,

(ModeL) and to be pasted thereto. The sides of the box are marked,respectively, 1 2 3 4 and the flap 5, the same side bearing the samenumber throughout the drawings. K marks the tucking-flap.

' In Fig. 4 the parts to compose the bottom of the box are shown atH andI, one of which, H, is square and the other a right-angle triangle whosebase equals the diagonal of the square. They extend down from the outer-I most side portions of the rectangle A B U 1), in manner as shown, andeach on its inner side is provided with a fly, as shown at r and s. Thisfly is to be turned within the box and pasted to the next adjacent side,in order to complete the connection of each bottom part with the twonext adjacent sides of the box. The square part of the bottom folds onits diagonal m 0 and the triangular part I on its altitude-line g g whenthe box is folded for transportation.

When the body of the box is unfolded into the form of a quadrilateralprism the parts composing its bottom lap on each other, the square partextending across the entire box and over and upon the triangular part.

The parts constituting the cover of the box may be made and arranged asrepresented at E, F, and G, or may be otherwise suitably formed andarranged.

I claim- In the folding box, the bottom thereof, composed of the twoparts H I, each part connected with the next two adjacent sides, and

arranged to lap on the other part and to fold diagonally, substantiallyas set forth.
